Abstract: 1,231,859. Screwing; jointing by forging; making nuts. G. A. TINNERMAN. 22 May, 1968 [22 May, 1967], No. 24503/68. Headings B3H and B3N. [Also in Division F2] A female fastener element 20 has an aperture having circumferential notches 23, the wall of the aperture has helical ribs 25, 26, 28 and 29, each rib starts at one end of the aperture and at a junction of a notch and the aperture, i.e. 27a, this starting point forms a cutting tooth and the radial height of the rib increases from 27a to 27b. The ribs are formed by punch members 24 which have slightly larger diameters than the aperture. The ribs of the two sets can be formed in the same two spaced helical paths such that when fitted to a stud having a plain shank low ends 27a of one set of ribs initially cut grooves in the shank and then high ends 27b of the other set of ribs deepen the same grooves. Reverse rotation is resisted by high ends 27b acting as teeth. The reverse torque can be increased by sharp blows on the shank to set the teeth of the ribs into the sides of the grooves in the stud. Sheet metal may not be sufficiently thick to take a ribbed aperture. Local thickening can be achieved by two opposed rams (42), Fig. 10 (not shown), having their operating ends saucer shaped, thus forcing the metal inwardly and upwardly. The fastener may be encapsulated in a synthetic resinous plastics base to give increased frictional engagement when assembled to a shank through its resistance to compression.

Abstract: 1,251,590. Lasers. INTERNATIONAL BUSINESS MACHINES CORP. 27 Aug., 1969 [30 Sept., 1968], No. 42564/69. Heading H1C. An image converter comprises a multimode He-Ne laser 12 having the end mirrors 24, 26 of its resonant cavity reflective to visible radiation but transparent to infra-red radiation to give a visible output, some of the modes being depopulated by an incoming infra-red image 15 so that the visible output is the negative of this image. The infra-red image of object 14 may first be amplified in intensity by one or more He-Ne lasers 10 having lenses 16, 20 separated by twice their focal distance f. A lens 22 backing mirror 24 directs the image into the laser cavity 12, in which there are of the order of 10<SP>6</SP> transverse modes, and lenses 28, 30 project the image on to mirror 26. This latter mirror is partially transmitting to visible radiation, and the visible output is projected on to a screen 36 by lens 34. Those modes occupying the same spatial positions as the incoming infra-red image are depopulated, and since He-Ne media have a greater gain at infra-red frequencies than in the visible spectrum, the output from modes depopulated by intense parts of the image is wholly infra-red. In less intense areas of the image, only a part of the output from such modes is infra-red, and hence the visible output on screen 36 is the complement of the infra-red input image. Mirror 26 may be made reflective to infra-red radiation so that the incoming image passes through cavity 12 twice. Other active media in which the gain is greater in the infra-red than in the visible waveband may be used, such as ionized mercury.

The two slotted gas ports 9 of an atmospheric gas burner are arranged with equal slopes so that the angle included between their axes is between 20 and 60 degrees, but preferably between 30 and 40 degrees, so that the gas jets impinge upon each other and mixing between air and gas is promoted by the resulting turbulence. The burner comprises a gas injector 1 with a supply bore 6 communicating with the gas ports 9 through a bore 7, and a burner body 12 with upper and lower portions 13, 14. The lower portion 14 has a Venturi restriction 15 below the point of intersection of the gas port axes and fits over the head 3 of the injector with lugs 16, leaving gaps 17 which form the air inlets. The upper portion 14 is rotatably mounted on the lower portion and its opposite walls 20 are flared outwards producing a flat, arcuate, slotted flame port 23 which is narrow relative to its depth, thus producing a back pressure in the mixing chamber which promotes mixing and stabilizes the flame.

Each dispensing operation performed by the first dispenser 14, 16, 18 steps a ten position switch 30 one position, and each complete cycle of the switch (i.e. each ten dispensing operations) advances a ratchet 40 one step anticlockwise. Also, each underweight batch detected by the second dispenser advances the ratchet 40 one step clockwise so that if the desired ratio is maintained the ratchet will however within the limits of a lost motion device 58 about a stable position. If however, the desired ratio is not maintained, the ratchet will move beyond the limits of the lost motion device to move a potentiometer 60 which will adjust the set point 20 of the first dispenser in a manner to restore the required ratio. The result of this method of control is that for the 90% of batches produced by the first dispenser that are above the pre-set minimum weight less material is given away than would so if the first dispenser were arranged to produce 99À9% of batches above the present minimum weight.
